Thanks for these links.
What a mess! In my case there would be no problem because
absolutely nothing was built against the new glibc.
However, I found another solution. I did not realize that
Gentoo offers a binary OpenOffice package. Installing
this openoffice-bin package now gives me an OpenOffice
that starts with the new glibc update.
So the new question is why does the binary from OO/LO
fail to start while the Gentoo binary shows no problem?
AFAIK they are the same package, but the directory structures
are different.
Anyway, I'm glad to have OO running.
